CESSPOOL-'W'ALL CONSTRUCTION.

Application led. November 21, 1923. Serial No. 676,160.

' oit Sayville, in the county oit Sutioll and State ot New York, have invented a new and improved Cesspoolddlall Construction, of which the following is a full, clear, and exact description.

lhis invention has relation to wall structures and to building blocks from which the same areconstructed and the saidinvention has particular reference to a wall and block construction for the erection ot cesspoois.

The outstanding object of the present invention is to provide a cesspool wall which will eiiectually permit ot the drainage of the contents therefrom, while at the same time functioning to minimize the filling of the oesspool with earth or sand Yfrom the exterior by its entrance through the drainage openings in the wall.

As a further object the invention contemplates a cesspool wall and block construction which is comparatively simple, inexpensive, and which is highly efficient in its purpose.

With the above recited and other objects in view, the invention resides in the novel construction set forth in the tollowing speci tication7 particularly pointed out in the ap pended claim and illustrated in the accom- ]Vianying drawings, it being understood that the right is reserved to ei'nloodimentsl other than those actually illustrated herein to the full extent indicated by the general meaning` ot the terms in which the claim is expressed.

In the drawings l .Figure 1 is a fragmentary vertical sectional view through a cesspool embodying a wall constructed in accordance with the invention.

Fig. 2 is a perspectiveview of one of the blocks from which the wall is constructed.

Referring to the drawings by characters of reference, the wall l() which is preferably constructed ot a plurality of building` blocks ll, has formed therein drainage openings l2 which are oil substantially elliptical or elongated shape 18 at the outer side oi' the y wall, the upper edge 14 of the openingbeing horizontal while the lower edge inclines upwardly and inwardly as at l5 and is :flattened as at 1G at its inner terminal. By iorn'iing the openings l2 in this manner it will be readily observed from Fig. l o'l the drawings that the inclined lower walls l5 ot the openings facilitate the drainage ot the contents of the cesspool while et'ectually acting as a battle to prevent or minimize the entrance of the earth or sand through said openings into the cesspool. By this arrangenient it is obvious that the necessity of cleaning out the cesspool will occur less frequently than where the openings are made straight. 1While the` wall is illustrated as constructed of blocks ll, it is of course to be understood that the same may be a solid poured cementitious wall with openings termed therein in lieu ot using the blocks.

l claim:

A ccsspool'termed ot a plurality ot rectangular concrete blocks, each provided with a plurality ot openings intermediate oi its ends and having in each end a recess forming with adjacent blocks openings, said openings each being` yconical with their smaller ends at the inner .face of the block.
